Onyx

[asmallchild]

So I finally got around to downloading Onyx.
Coupla questions:

1) Do I even need it? (I was told that Macs perform routine cleanup if I put the unit to sleep instead of shutting it down)

2) Any hints on running this? (I was told it was the Windows equivalent of CCleaner. Needless to say, it looks a lot more complicated. I was planning on just using the default settings but even with those, I'm not quite sure what I'm doing )

Nah... you don't really need it, but it can be nice from time to time for cleaning a bit up, especially when thing are acting up a bit.

I actually prefer MainMenu to OnyX, as I think that is a bit more intuitive and user friendly (though I know OnyX also has its supporters):

If you aren't experiencing any problems, then don't run it! Your Mac builds cache files for a reason, deleting them can actually slow your Mac down. They can get corrupted, but deleting them proactively won't protect you. Same with repairing permissions, unless you are experiencing a problem, repairing permissions is pointless.
There is even quite a bit of controversy about defragging.

No controversy you don't need to
